- Graviton processors, launched in 2018, enhance performance and cost-effectiveness for cloud workloads.
- Graviton 2, released in 2019, provides significantly improved performance and memory capabilities.
- Graviton instances can deliver up to 40% cost savings while maintaining high performance.
Advantages of Amazon EC2
- Extensive selection of instance types to suit various workloads, from T3 instances to instances with 96 processors.
- Scalability allows users to adjust resources dynamically, with auto-scaling based on defined metrics.
- Nitro technology enhances performance by offloading network and storage management tasks, ultimately improving responsiveness.
Reliability and Security
- EC2 operates across 24 Regions and over 76 Availability Zones, ensuring a 99.99% SLA commitment for availability.
- Security standards are stringent, with default security measures established for every instance, minimizing attack surfaces.
EC2 Instance Families
- EC2 is categorized into five families: General Purpose, Compute Optimized, Accelerated Computing, Memory Optimized, and Storage Optimized.
- Each family offers various instance types optimized for specific workloads, allowing for tailored infrastructure solutions.
- Instance naming conventions indicate characteristics such as processor type and performance level.
General Purpose Instances
- General Purpose instances balance CPU, memory, and network capabilities, suitable for web servers and microservices.
- Includes burstable T family instances which allow for performance boosts through earned CPU credits for intermittent workloads.### EC2 Instance Types and Performance
- T2.small instances utilize burstable credits, consuming 1 credit per minute during high CPU performance workloads. After credits run out, performance returns to baseline.
- Exceeding credit allotment incurs extra charges, but still allows processing of requests.
- M family instances (M4, M5, M6) offer a balance of compute, memory, and network resources, supporting multiple processors: Intel Xeon, Graviton 2, and AMD.
Specialized EC2 Instances
- A1 instances are powered by Graviton processors, suitable for scale-out workloads, particularly with open-source programming languages (e.g., Java, Ruby, Python).
- Mac instances are built on AWS Nitro, offering access to macOS for development with Apple's Xcode IDE.
- C series (C7, HPC6a) are Compute Optimized instances meant for compute-intensive tasks like high-performance computing, video processing, and machine learning.
Accelerated Computing Instances
- Accelerated Computing instances (P4, G5, F1) include GPUs for intensive processing tasks, such as graphics and machine learning.
- P family (P2, P3, P4) instances facilitate machine learning with multiple NVIDIA GPUs, drastically reducing training time.
- G5 instances are tailored for machine learning using NVIDIA A10G for versatile graphics and modeling.
Memory and Storage Optimization
- R family (R6, X2) are designed for memory-intensive applications, supporting real-time analytics and in-memory databases.
- X2 instances achieve up to 50% better price-performance than X1 instances, with High Memory instances offering up to 24 TB RAM.
- Storage Optimized instances (H1, D3, I4) provide high disk performance and include HDDs for large datasets. D3 significantly accelerates read/write operations compared to D2.
Pricing Models and Optimization
- The EC2 pricing model includes On-Demand (pay per use), Reserved Instances (long-term discounts), Savings Plans (flexible spending across services), and Spot Instances (up to 90% off but can be interrupted).
- Recommended for varying workloads, combining options optimizes cost and performance, as seen in an e-commerce context with auto-scaling.
AWS Compute Optimizer
- AWS Compute Optimizer analyzes over 140 instance types and suggests cost-effective options based on workload utilization.
- It employs machine learning to make instance size recommendations, allowing performance simulation to assess compliance before implementing new instance types.
Amazon Machine Images (AMIs)
- AMIs are essential for launching instances, containing OS configuration, launch permissions, and root storage details.
- Supported operating systems include various distributions like Ubuntu, Red Hat, and Windows Server with multiple architecture options (e.g., 64-bit).
Best Practices for EC2
- Access management involves using Identity and Access Management (IAM) with least privilege principles for users and roles.
- Regular OS maintenance is crucial, as users are responsible for security and updates.
- Data management varies by storage type; EBS-backed instances retain data post shutdown, while instance storage does not.### Data Persistence in EC2 Instances
- Instance store data is lost upon instance shutdown; for persistent storage, use an EBS volume or S3 bucket.
- EBS volumes provide mountable storage that maintains data post-shutdown, albeit at a lower speed compared to instance stores.
- Recommended practice: allocate one EBS volume for the OS and another for data.
- For instance storage persistence, implement a replication strategy using tools like Hadoop or Spark across multiple EC2 instances.
Resource Management in EC2
- AWS allows tagging of instances with metadata to organize and manage resources effectively.
- Tags can include information such as department, billing, and security groups.
- Tags assist in differentiating workloads for automation and billing purposes.
AWS Limits and Management
- AWS enforces service limits to prevent unexpected costs and unauthorized access.
- Soft limits (e.g., 5 for Amazon VPC) can be increased upon request; hard limits refer to strict caps.
- Default limits include 20 instances and 5 Elastic IPs per region, which can be adjusted with AWS support.
Backup and Recovery in EC2
- Backup strategy essential for EBS volumes includes using EBS snapshots and AMIs for instance configurations.
- Deploy critical components across multiple Availability Zones to enhance application availability.
- Elastic IP allows for fixed IP assignment to maintain traffic routing during failover scenarios.
- Test failover solutions to ensure minimal disruption during backup instance activation.
Amazon Elastic Load Balancing (ELB)
- ELB offers advantages in distribution of traffic, enhancing scalability and reliability across EC2 instances.
- ELB conducts health checks on instances to monitor their availability; unhealthy instances stop receiving traffic.
Types and Rules of ELB
- ELB rules consist of conditions (criteria for routing) and actions (what to do if criteria is met).
- Listener rules forward traffic based on protocol and port, while target group rules manage traffic distribution.
- Host-based routing allows directing traffic to specific services using domain names; path-based routing directs traffic based on URL paths.
- Query string rules enable routing based on key-value pairs in URL parameters.
Elastic Load Balancer Types
- Classic Load Balancer (CLB) uses methods like round robin, least connections, and IP hashing for traffic routing; considered legacy.
- Application Load Balancer (ALB) operates at Layer 7, allowing content-based routing based on HTTP request features like URL path and headers.
- ALBs support advanced load balancing techniques and improve resource management for applications.
